Speech recognition model training method and device, and electronic equipment

The invention discloses a speech recognition model training method and a device, and electronic equipment, and relates to the technical field of machine learning. The speech recognition model trainingmethod comprises the steps of: determining a plurality of differential syllable label sequences from the second syllable label sequence; determining a target differential syllable label sequence according to the plurality of differential syllable label sequences, the target differential syllable label sequence being a union set of the plurality of differential syllable label sequences; generatinga third syllable label sequence according to the target difference syllable label sequence; and performing speech recognition model training according to the first syllable label sequence and the third syllable label sequence to obtain a mixed speech recognition model. The hybrid speech recognition model can be trained according to the first syllable label sequence and the target difference syllable label sequence, and th
